Claims
- 1. A method for introducing and metering the liquid treatment medium effective for reducing NO.sub.x into the waste gas flow in combustion processes for reducing the NO.sub.x content of the waste gas flow, comprising the steps of:
- (1) pressurizing the liquid treatment medium at a first pressure;
- (2) pressurizing a liquid carrier medium at a second pressure;
- (3) delivering said liquid treatment medium and said liquid carrier medium in adjustable amounts to a mixing chamber to form a liquid mixture at a third pressure; and,
- (4) spraying said liquid mixture into an area having a fourth pressure to contact the waste gas flow and reduce the NO.sub.x content;
- wherein said liquid mixture is atomized solely by a single-component nozzle positioned to spray said liquid mixture into the area and said spraying step is effected when said third pressure exceeds said fourth pressure.
- 2. The method of claim 1, wherein said first pressure is equal to said second pressure.
- 3. The method of claim 1, wherein said mixing chamber has a maximum volume which is emptied by said spraying step in a few seconds.
- 4. The method of claim 1, wherein said mixing chamber has a maximum volume which is emptied by said spraying step in no more than 30 seconds.
